How about not giving it a name at all, but rather making it a hidden
property of a table? Then, if you want to get to the value, one would call
a function like getn(table). I wonder how much existing code that would
break-- that is, how many people use table.n as a rough synonym for getn()?
No matter what name you pick, *someone* will eventually toss data in a table
that's the same name as this variable. I love Lua, but this is one of my
pet peeves of the language. The size of a table should be an intrinsic
property of the table-- not a member of the table. I can see the value of
making it optional-- but not the value of making it a member.
